Yes. Of course. I make use of fixed deposit accounts to earn some good interest. It is definitely a good investment option. While giving a fixed rate of interest based on the amount and the period you prefer, you can also close the fixed deposit account whenever you want and use the money for your son's education, daughter's marriage or for any other emergency. I always liked the fixed deposit schemes and invest in it whenever it is possible for me to invest that extra cash if any, I may have at point of time during the year. Investing, whether in fixed deposit schemes of banks or somewhere else ( I prefer fixed deposit schemes of the banks only) gives you the confidence that you are in control of your money and you are not spending unnecessarily.
